I-extruder yerabha iyimishini eyisisekelo embonini yerabha futhi ingenye yemishini ebalulekile ethinta ikhwalithi yomkhiqizo. Idlala indima ebaluleke kakhulu enqubweni yokukhiqizwa kwamathayi nemikhiqizo yerabha. Ukuthuthukiswa kwe-extruder yerabha yangaphandle kuye kwabhekana ne-Plug extruder, i-screw type hot feed extruder, i-common cold feed extruder, i-main and assistant thread cold feed extruder, i-cold feed exhaust extruder, i-pin cold feed extruder, i-Compound extruder nezinye izigaba. I-extruder yerabha isetshenziselwa ukucindezela, ukuhlunga kanye nokuhlanganisa imikhiqizo yerabha encane. Izici zesakhiwo: I-screw kanye ne-sleeve yangaphakathi zenziwe ngensimbi ene-nitrided, enokumelana okuhle nokuguguleka kanye nobulili bokumelana nokugqwala.
Ukukhishwa kwezikulufo kwenhlanganisela ye-raber extruder kungenye yezinkambu ezindala zobuchwepheshe be-extrusion, okungalandelwa emuva ngekhulu le-19. Ama-extruder enjoloba ngokusobala ahlukile kuma-extruder e-thermoplastic. Okokuqala, ukukhishwa kwenjoloba Kwenziwa ekushiseni okuphansi (kufika ku-130 °C). Okwesibili, imichilo yenjoloba ivame ukungezwa ekukhishweni kwenjoloba (ezimweni ezingavamile kuphela, ama-pellet ayengezwa), futhi awashintshi isigaba noma ushintsho lwesigaba ohlelweni lwe-screw extruder. Umphumela omkhulu wokujiya. Lokhu akufani nama-thermoplastic. Ama-Thermoplastic kufanele acutshungulwe ekushiseni okungu-180^-300°C (noma ngaphezulu) ku-screw extruder, futhi izinhlayiya eziqinile eziphansi zivame ukungezwa ku-extruder. Lapho ama-pellet ehamba phambili ku-screw, umthombo oncibilikayo uyaqina.
Izinto zokukhipha irabha zivame ukuhlukaniswa zibe imishini yokondla eshisayo kanye neyokondla ebandayo. Ku-extruder yokondla eshisayo, inhlanganisela yerabha ishiswa ngesenzo somshini wokugaya ovulekile, futhi lezi zintambo zerabha ezishisayo ziyasikwa futhi zikhishwe njalo. Zondla kusuka emshinini. Ku-extruder yesikulufu sokondla esibandayo, umugqa werabha ekushiseni kwegumbi uyangezwa ku-extruder. I-extruder yerabha ivame ukuhlukaniswa ngokuya ngokuthi isetshenziselwa yini ukukhipha umoya.
Uhlobo lwe-extruder yerabha
I-extruder yerabha iyimishini eyisisekelo embonini yerabha futhi ingenye yemishini ebalulekile ethinta ikhwalithi yomkhiqizo. Idlala indima ebaluleke kakhulu enqubweni yokukhiqizwa kwamathayi nemikhiqizo yerabha. Ukuthuthukiswa kwe-extruder yerabha yangaphandle kuye kwabhekana ne-Plug extruder, i-screw type hot feed extruder, i-common cold feed extruder, i-main and assistant thread cold feed extruder, i-cold feed exhaust extruder, i-pin cold feed extruder, i-Compound extruder nezinye izigaba.
Izinto zokukhipha irabha zihlukaniswe kanje: uhlobo lwe-plunger, uhlobo lwesikulufu, uhlobo olujwayelekile, uhlobo lokuphakelayo okubandayo, uhlobo lwephini, uhlobo lwe-compound. Esikhathini esizayo.
I-Jinan Power Roller Equipment Co., Ltd iyinkampani yangasese yesimanje equkethe ucwaningo lwesayensi kanye nokukhiqiza. Imikhiqizo esiyinikezayo yile: Umakhi we-Rubber Roller, Umshini Wokugaya we-Rubber Roller, I-External Cylindrical Grinder, Umshini Wokuhlela we-Emery Belt, I-Rubber Internal Mixer, i-open mixer mill, Ithuluzi Lokulinganisa Elizenzakalelayo Ngokugcwele, Ikhanda Lokugaya kanye Nokufakwa Kwemishini.
